Structural Design of Goldman Sachs West Canopy

Goldman Sachs West Canopy 2.jpg
Project Overview: 
The 350-foot canopy is a study of folded planes of glass, both at the top and bottom and supported by 86 different cantilevered tapered, bent structural steel ribs.
McLaren's Role: 
McLaren helped develop the I-shaped profile for the tapered cantilevered canopy members. Back-to-back tapered channel-shaped bent plate members with welded top and bottom flange plates were used. McLaren also developed a structural system that permits incremental thermal movement along the length of the canopy, which is attached to the building. The building itself is not subject to thermal movement. Following design of the structural systems, McLaren produced detail shop drawings including all of the bent plate components for the structural steel frame, for the fascia panels and their attachments, and for the custom attachment of the glass at both the top and bottom canopy planes. McLaren also developed a custom system to permit differential thermal movement of the individual glass tiles at the bottom glass plane.

Long Island Expressway/Grand Central Parkway Bridge Replacement

LIE & GCP Bridge Replacement.jpg
Project Overview: 
This project involves the replacement and widening of three (3) 3-span bridges at the Long Island Expressway (LIE) and Grand Central Parkway (GCP) interchange. Each of the three (3) bridges carries LIE traffic over the GCP and GCP service roads. The replacement of the bridges and various approaches is taking place over six (6) construction phases; to maintain and protect the continuous flow of traffic on both the LIE and GCP mainlines, service roads, and access ramps.
McLaren's Role: 
McLaren developed the erection sequence and means/methods of construction for each of the six (6) phases of steel erection. For each phase, McLaren prepared a comprehensive submittal which detailed the step-by-step erection sequence and procedures and included the required supporting calculations and drawings; all in conformance with AASHTO, NYS Steel Construction Manual, NYS Bridge Design Manual, OSHA and standard industry safety practice.

Magnolia Mound Visitors Center

Magnolia Mound Visitor Center.png
Project Overview: 
The mission of the historic Magnolia Mound, established in 1791, is to illustrate and interpret the French Creole lifestyle.
McLaren's Role: 
McLaren worked with Trahan Architects -- on this award winning building that seamlessly works with the landscape of the historic Magnolia Mound -- providing construction administration services and glazing system design. Services included the review of concrete mix design, review of the reinforcing steel shop drawings, review of the trellis design, response to RFI’s, participation in project meetings, and feedback for the all-glass wall change order. The building is 4,200 square feet.

NYSOGS 95 Walsh Retaining Wall

NYSOGS 95 Walsh (2).jpg
Project Overview: 
On March 11, 2015 a slope failure occurred that impacted a senior living building located at 95 Walsh Road causing the evacuation of the building. McLaren responded immediately that evening to observe the retaining wall and slope failure, which exposed a portion of the croton aqueduct built in the 1830’s.
McLaren's Role: 
McLaren determined the resulting slope failure was predominately mud, and excess water behind the wall appeared to have caused the failure. The main challenge was to not further destabilize the slope while stabilizing the remaining walls. McLaren recommended several next steps to the client. The ensuing effort, under an Executive Order from the Governor of NYS, was to design and construct a new 320 foot long tied back soldier pile wall with concrete form lined lagging in front of the existing stone gravity retaining wall as part of a Design-Build contract with Moretrench.

Battery Park Perimeter, Bikeway, Oval and Woodland Reconstruction

109455 Reconstruction of the Battery Park and Perimeter Bikeway 2015-06-12.JPG
Project Overview: 
The project reconstructed the path system in front of Castle Clinton to provide a great lawn with more open space. A bikeway was constructed along the north perimeter of the park that completed the linkage at the South Street Ferry with the West Street greenway.
McLaren's Role: 
McLaren provided full preliminary design and final contract documents for the completion of landscape areas and bikeway within the park, foundation design for the re-installation of 13 monuments, as well as permitting and construction administration services. McLaren provided Quennell Rothschild Partners with civil, geotechnical, structural, and other related services in connection with their New York City Department of Parks and Recreation contract to develop design and contract documents for the reconstruction of areas of Battery Park.
